ALLOCATION TABLES
Allocation tables, also known as hierarchy tables, describe a hierarchy of regions where the smaller regions fit precisely within the larger regions. The ASGS represents a structural hierarchy where areas at the smaller levels aggregate directly to those above them. An example of this is the relationship between SA1s and SA2s where an SA2 contains one or more whole SA1s. Allocation tables are usually supplied as text files.

Allocation tables only describe the relationship within a single structure and cannot be used to convert data from unrelated structures or data over time. It should also be noted that allocation tables cannot be used to disaggregate data from the higher levels of the ASGS.
